Will Silvervine make my cat addicted? Is it harmful to their health?
No! Silvervine is a green, natural plant. The actinidine and other compounds in the plant are detected by a cat's olfactory system, sending signals to the brain through their sensory neurons. It does not directly stimulate the brain, so it does not interfere with the body's normal physiology. Once the cat stops having access to silvervine, they will return to normal behavior over time.
